intoxicant

This term carries a clinical or legal tone, often appearing in statutes, medical reports, or formal warnings. It focuses on the chemical property of a substance to alter consciousness or impair judgment, rather than the social or recreational aspect of its use. As a countable noun, it refers to specific types of substances. When used in a general sense to describe the quality of being intoxicating, the related adjective "intoxicating" is more common.
